Batentedfblar. 25, 1913. a 'nvncma ni'd ocenie; 18, 1812. :'riinifsfst it, conce'rn of1Michigan, haye invented certinnewgand useful Improvements in Blowels for Boilers; of which' the lfollowing is specification, reference being had therein tol 'the accompanying drawings. f `I n the application'of steam bloivers to water' *tube boilers -itis necessary -in order to obtain thefgreatest ,elficiency' 'thatthe elean'ing` jets be' pi'ojected across and throughftubes in V'planes that are substan- .tially;parallel-thereto. In mounting such device'sn'pon; a water tubeboiler it.1salo.

desirble that 'the openings in the masonryat'which the headersthat carry the, jets are appliedg'be; arran'ged at su "stantially right angle's-.tothe nmsonrycou se's forconvenience construction. VFnrthermore openinthe `forml of Smanhole or cleaning` doorsfare frc uently found in such masonry and itis deslrable that they be available for nein the application of a blower. 'i inventionj-relates vto'a 'blower ,for water. tubeboile'rs thatis adapted for application to the maso'nry and-closes the side of the boiler through upright openings thereinand .that i adjustable so that. the Cleaningr jets may be readily made to sweep the tubeswhether the latter be horizontal or as'm'o're frequently, -inclined The invention also includes features that provide for` its easy manipulationtwithout danger to the operator-l and which .insure suflic'iency combined with simplicity of construction.l

The invention 'consists in the matters here'- inafter set -fo'rth and pointed out in the claims.

'In' the drawings, Figure 1 is a view in side elevation of a masonry 'setting of a water tube boiler with a portion of a blower that embodies vthe invention jmounted thereon' Fig. 2 is a view, partiallyin -elevation and partially inatransverse section, of the blower, the 'masonry settin and the adjacent tubes of aboiler; F ig. 3 is a view in section ltaken on orabout line III-;III of Fig. 2, the boiler tubes being omitted;- Figs. 4, 5 and '6 are views in detail of a nozzle, tip and means for swinging the latter.

As herein shown in preferred form a supily pipelV fromhi a 'suitablesouree steam l.has one .or more ybranches `indicated alt 2 each of which is connected through suit- `the outer sleeve of aitelescoping or Slide Joint. Preferably -thisouter member, which is transverse to-t-he face of' the masonry fittin, is formed 'integrall with or secured tora racket 6 that isarranged to span an ing tube 7 that telescop'es' with the sleeve through a suitable stufling'box or gland 8, is supported at its outer end by lateral lugs -o`r gibs 9 which .slide on guide ways 10 of 'the telescop'ing joint. A T ll A;cofnstitutes the inner end portionof 'the tube 7 and carries an upright header 1-2 which is in substantial" alinement 'with Vopenings shown at 13 in a vthroatfpIate 14 zatthe mouth of. the setting opening. `VThis plate may have guides 1'5 or thelike for retaining a cover plate whichelose's the openings when the blower is'notfin-use. Arms 16 extend laterally fromv the header 1:2 and are spaced in staggered relation to the tiers of water tube indicated a t 17 'of the' boiler.

the nozzle. wheel 23 secured to the nipple 19. concentric to the axis of'oscillation offith'e lattenfmay be turned by means of a Chain Qfcable or thev l'ikethat prasses along 'longit-udinal grooves indicated at `25 in the nozzle 18 and encirclesa pulley wheel or sprocket 26: .A shaft 27 is journaled in suitable bearings 28 at each end of the header 12 in naillel spaced relation thereto and the pulleysor lunder pressure,'usually the steam dome'of" the boilr'to which the blower is attached,v 4
